We were using OpenGrads to generate .PNG image for significant wave height from .ctl files (Generated using OpenGrads from GRIB files downloaded from NOAA). Google uses Web Mercator projection and OpneGrads does not support this projection. So Image does not fit to the boundaries.
I Googled about this Problem, and found that GDAL supports atleast Web mercator projection. But I can not find any command to generate Image from .GRIB/.GRIB2 files.
Any help, will be appreciated.
